I tried GoPro and found it totally frustrating. It didn't work as the instruction manual said and software upgrades failed. I took it back and got the Ion Air Pro wireless and have been much more satisfied.

I was going to post references to a few some AirPro videos of solo sailing on Lake Michigan, but the system here stopped me. Perhaps you can figure out the URL from (youtube.com) + (\) + (channel/UCevkPHlBIzghWsjultU8oiA?feature=watch)
